 dependencies {
     providedCompile 'javax.servlet:javax.servlet-api:4.0.1'
 }
 gretty {
   httpPort = 8080
   contextPath = '/'
 }
 repositories {
    jcenter()
 }

#3 Clean up and add some Resources

Go into src/main/java and delete jee.test.App.java, you can keep the package name
Go into src/ and delete the whole test directory as shown in the screenshot

Open Project properties "CMD+I" or Right click on your Project and choose "Properties"
Navigate to Project Facets and click on convert to faceted form...

Right Click on your Project and choose "Gradle → Refresh Gradle Project"

Now add a new JSP "index.jsp" to your webapp folder


<%@ page language="java" contentType="text/html; charset=UTF-8"
 pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Home Page</title>
</head>
<body>
 <%
  for (int i = 0; i < 5; i++) {
 %>
 <h1>Hello from JSP</h1>
 <%
  }
 %>
</body>
</html>

Add a new Servlet, from the Button "Add Servlet"

Since we don't care which type of requests we receive (GET,POST, ...), we will only implement the service method.

Start your Application Server with ./gradlew appRun
Open at http://localhost8080
